C230M (2018) Oxygen Transmission Rate Test System

C230M Oxygen Transmission Rate Test System is designed and manufactured based on coulometric sensor method (aka. equal pressure method) and conforms to the requirements of ISO 15105-2/ASTM D3985. This instrument can be used to measure the oxygen transmission rate of barrier materials with high, medium and lower barrier properties with a wide testing range and high testing efficiency. The instrument is featured with patented design of integrated block consisting of 3 test cells. Equipped with high precision sensors and professional computer-controlled system, the instrument can regulate and control the temperature, humidity and flow rate properly, which guarantee the testing sensitivity and repeatability of test results. C230 is applicable to determination of oxygen permeability of plastic films, sheeting, paper, packages and other relative packaging materials in food, pharmaceutical, medical apparatus, daily chemical, photovoltaic and electronic industries, etc.

Test Principle

The pre-conditioned specimen is mounted between the upper and lower chambers at ambient atmospheric pressure. One chamber contains oxygen or air and the other chamber is slowly purged by a stream of nitrogen. Due to the concentration difference between the two chambers, oxygen molecules permeate through the specimen into the nitrogen side and are taken to the coulometric sensor where proportional electrical signals are generated. The oxygen transmission rate is then obtained by analyzing and calculating the signals. For package samples, high purity nitrogen flows inside the package, and oxygen or air flows outside.
